New Product Debut | Made In China Security Control 10G Fiber NIC AVAILABLE

The new product debut, shocked the market! Shenzhen Lianrui Electronics Co., Ltd. (hereinafter referred to as Shenzhen Lianrui) will launch two domestically-controlled and safely controllable 10 Gigabit Ethernet fiber optic network cards with independent intellectual property rights - LRES1002PF-2SFP+ and LRES1003PF-SFP+. The fiber-optic network card equipped with the domestic main controller has various functions such as LAN performance acceleration, network security, network convergence, network virtualization, data center bridging, etc. The single-port communication bandwidth is 10Gbps and the number of logic gates of the chip reaches 18,000,000, on-chip SRAM capacity of 25Mbit, support PCIE3.0 serial bus host interface and SFI / KR and other Ethernet interfaces.

Shenzhen Lianrui (LR-LINK) newly introduced the domestically-controlled and controllable 10Gb Ethernet optical fiber network card using the Netswift Technology SP1000A controller. The controller passed the scientific and technological achievements appraisal organized by the China Command and Control Society, and the identification results showed its main innovation. The points are:

1.A method for implementing super-multiple DMA queues is proposed. The hierarchical DMA queue architecture is designed innovatively to effectively solve the problem of realizing the consumption of a large amount of resources in the super-multiple DMA queue. Compared with the traditional method, it saves resources by more than 50%.

2. Invented a message fragment transmission method, which broke through a large number of key technologies such as data packet concurrency state cache and QOS arbitration, and solved the problem that the on-chip storage space is heavily occupied by cross-slices. Compared with the conventional method, packet transmission. The average latency is reduced by 30% to 50%, improving the overall network transmission performance.

3.The opaque security mode of the network controller configuration is implemented for the first time. The method of configuring the NIC chip data path after the server software is authorized in the opaque security mode is designed and implemented. The firmware self-configures the working state, effectively preventing the malicious code pair attack network,improved the security of network systems.

4. Breaking through the key technology of seamless network switching of virtual machine hot migration, solving the problem of packet loss during network routing switching, avoiding the data retransmission caused by data packet loss and the instantaneous rise of network load, greatly improving the APP performance and stability.

5. Innovatively designed a programmable flow table structure supporting overlay network layer protocol, realizing dynamic loading of ACL and routing table, and dynamic configuration of physical network topology, providing a technical way to support software-defined network.

6.A technical method for optimizing the internal DMA logic of the chip is proposed, which realizes the parallel processing of the data indicator and the data message, and the parallel operation of the QOS and the queue arbitration at the transmitting end, which can greatly increase the actual packet transmission rate.

The evaluation results show that the controller has significant innovations in the layered DMA queue architecture, seamless switching of virtual machine hot migration networks and cross-slices. The overall technology including average transmission delay and actual packet transmission rate have reached the international advanced level.

At present, the controller has passed the performance test and safety test of the China Electronics Technology Standardization Research Institute, the China Information Security Evaluation Center, and has demonstrated excellent performance in authoritative testing and application on X86, SW, FT and other platforms.

Through the comparison of the main controller of the brands, the main control of the SP1000A in the netswift technology has reached or exceeded the mainstream products of the same type in terms of overall technical and functional performance indicators. (Y means support, N means not support)

1.Protecting  information

In summary, Shenzhen Lianrui (LR-LINK) newly launched the domestically-made security controllable 10 Gigabit Ethernet fiber NIC has excellent performance in terms of overall technical and functional performance indicators. Complete localization means that the products have the advantages of independent controllability of technical capabilities, controllable intellectual property rights, controllable production, and control of self-control, which are of great significance for breaking foreign monopoly and ensuring national information security.

Welfare:
Shenzhen Lianrui (LR-LINK) newly launched a domestically-made secure and controllable 10 Gigabit Ethernet optical network card with independent intellectual property rights will be unveiled at the China International Optoelectronic Exposition (CIOE) from September 5 to 8, 2018. We sincerely invite you to take the time to come.
